The Brown Stair: Brown Lacquer
002550
This series of prisms demonstrates to the child the change in width (breadth), while the length remains constant. Practice with The Brown Stair indirectly prepares the child for concepts in plane geometry, area and volume. The hardwood prisms are crafted in precise progressions from 1 x 1 x 20 cm to 10 x 10 x 20 cm.
